Storing Milk

All milk should be stored carefully in sterilised containers. Contaminated milk is dangerous for your baby causing diseases such as gastroenteritis (infection of the gut). Store prepared formula in the back of the refrigerator, not in the door. Discard unused formula after 24 hours.
Storage of Breastmilk
Great care needs to be taken when storing breastmilk, as contamination can easily occur. Reduce the risk by using sterile containers and always wash your hands.
Breastmilk can be stored in plastic or glass containers. Small sterile bags, specifically designed for storing breastmilk are available from your pharmacy. If you intend freezing the milk, pour it into a sterile container, label it and fill the container three-quarters full. Make sure you have sealed the container correctly then cool it first in the refrigerator, before placing it in the freezer.
Breastmilk should not be frozen for long periods of time as the milk can be contaminated by bacterial growth and if offered to your baby can cause infection and illness.
Generally frozen breastmilk can be stored:
- In the freezer section of a single door refrigerator for a maximum of 2 weeks
- In the freezer section of a refrigerator with a separate door for a maximum of 3 months
Thawing and use of breastmilk:
- Placing frozen breastmilk in a container of warm water to rapidly defrost. Shake milk gently before use. The defrosted breastmilk in this way must be used or discarded within 4 hours, even if refrigerated
- Take frozen breastmilk and allow to partially defrost for 10 to 20 minutes (depending on amount). Shake milk to a ‘slushy’ consistency then place in refrigerator to complete defrosting. Defrosted breastmilk in this way must be used or discarded within 24 hours of removal from freezer
Do not thaw breastmilk in a microwave as this will alter its composition. Instead, place the container in warm water and shake well before giving to baby.
